One of the highest smoke output of any electronic cigarette: 25% more than other leading brands from their FlavorMax Cartomizers (each cartomizer is about equal to 30 regular cigarettes--1.5 packs--or 360 puffs.
Batteries are good quality and last
Long lasting, great tasting flavor cartridges
Excellent customer service
Two-piece design is attractive and easy to use
Choice of short or long battery; short is more like a classic cigarette and long gives you more staying power.
Designer batteries and other embellishments available

Cons

Expensive: one of the most expensive on the market
No manual battery option (this means you rely on your own lung power entirely to warm up the cartridge and start the vapor)
Less of a "throat hit" to the vapor than other brands, meaning vapor is not as rich

Green Smoke Basics

Seven flavors: Absolute Tobacco, Red Label Tobacco, Tobacco Gold, Menthol Ice, Mocha Mist, Vanilla Dreams, Smooth Chocolate, Variety Pack (more than NJOY, far less than Vapor4Life)

Free shipping on all orders over $25
Limited lifetime warranty
30 Days, 100% Money Back Guarantee

The Green Smoke Bottom Line

A good product if you can afford it, and best if you need customer service and cute add on options. If you need to economize, this isn't the brand for you. If you are a longterm smoker and have serious flavor needs, proceed with caution and try it first.

The Wrap Up

Although e cigarettes are not officially a smoking cessation tool, many smokers are using them in just that way. That's why the features of each brand are so important to consumers. Green Smoke is the most premium of these three brands which is reflected in its customer service more than anything else. NJOY is one of the oldest brands on the market, and has kept its offerings simple--just what some old school smokers are looking for. Vapor4Life is a trendier-feeling brand, from multicolored, print battery options to tropical fruit flavors--and its low prices reflect that "take a chance" spirit.
